I created a router, and in it I created a interface for the router:
But you see, the status all is Down, how to debug the interface? why it is down?
EDIT-1
In the /var/log/neutron/server.log, I use cat server.log | grep router, get the below information:
[![enter image description here][2]][2]
Finally, I find in my /etc/neutron/plugins/ml2/ml2_conf.ini configuration file, I did not configured the ml2 type_drivers and mechanism_drivers. So I config them:
# openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 type_drivers flat,vlan,vxlan
# openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 mechanism_drivers linuxbridge,l2population
And restart the neutron-server:
systemctl restart neutron-server.service
systemctl restart neutron-l3-agent.service
Now, it works fine.
You can use linux namespace ping as well
ip netns list
identify router id and identify the interface - sudo ip netns exec qrouter-**************** ifconfig
Use the ping utility to ping from router - sudo ip netns exec qrouter-**************** ping a.b.c.b
I'm working on RHEL 7 with Openstack 14 on VMware VM, the router interfaces on neutron is down on horizon, I treid solutions with vBridge or without vBridge, didn't work also your solution didn't work with me, I tried the following links:
https://www.linuxtechi.com/install-use-openvswitch-kvm-centos-7-rhel-7/ (https://www.linuxtechi.com/install-us...)
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/8/html/networking_guide/sec-connect-instance (https://access.redhat.com/documentati...)
https://ask.openstack.org/en/question/25234/one-router-port-is-always-down/ (https://ask.openstack.org/en/question...)
didn't work, my VM External eno16377736 IP is 192.168.43.77
I used the following to install openstack:
systemctl disable NetworkManager
systemctl stop NetworkManager
systemctl disable firewalld
systemctl stop firewalld
setenforce 0
systemctl restart network
systemctl status network
subscription-manager list --available
subscription-manager attach --pool=

rpm -q --whatprovides rubygem-json ###### rubygem-json-1.7.7-20.el7.x86_64
yum install -y openstack-packstack
also this didn't work with me:
ovs-vsctl add-br br-ex
ip addr add 192.168.43.77/24 dev br-ex
ip addr flush dev eno16777736
ip addr add 192.168.43.77/24 dev br-ex
ovs-vsctl add-port br-ex eno16777736
ip link set dev br-ex up
virsh net-define /tmp/ovs-network.xml \ Network ovs-network defined from /tmp/ovs-network.xml
and this:
